I really like the well lit night shot. I assume you have the moon behind the gable to give you that nice sky glow. That is very effective along with the window light shining on the snow and the framing of the house.
There is one slight bump in the snow near the bottom on the right. It is barely noticeable. But I would be tempted to crop just up to that point as it is a slight distraction. There is a dark drift higher on the left - its larger size allows it to be read as a drift, and so not a distraction.
"Snowshoes out. Mission accomplished" is a really effective picture. Up close and personal. The kid's expression (despite the squint) and the hair blowing in the breeze are both good. The bag or cloth on the right side is little ambiguous, and perhaps it would be better not in the picture.
The background also adds a lot to this photo. There is just enough texture in the snow so that it is not a bright void. The people are nicely spaced with few overlaps among them. The only overlap that is distracting is the dog and person with the light coat. How do you ask a dog to stand still? You can't, and the stride through the picture is great, so I think we can accept the overlap as an inevitable necessity.
These are both very effective in black and white.
